Change imported model orientation
You can easily fix this, no need to move the camera to compensate for the orientation of the mesh. You can rotate the mesh by adjusting the rotation in the properties tab, you can also use the mesh tab. You can also do this for many method for multiple objects. Just select the object that need to be fixed and rotate them via r x 90



You can also fix this when you import the mesh. I am assuming you are importing as .obj but this should also work for others. When you import the mesh set the Foawrd axis to -Y and the Up axis to Z.
